what how

This and that

This and that, are 2 short words
That can mean lots and much more
This is here, and in this world
That is there, and there it was

This is now, (& don't ask me how?)
That is then, (somewhere somehow?)
This is what I see, feel and I am
That is what I felt and was to be

This is what I hold now onto
That is what I just let go
This is where I make a stand
That is where I used to bend

This and that, they pull apart
That end, to this end, of time
This one is out here in front
That one is out there, behind.
